Hello,

I have this situation:
  • A train company operates a route between stations A, B and C.
  • Riders can take a train from A to C or B to C. No trips from A to B are allowed.
  • In the winter there's no issue with this route.
  • In the summer, due to weather conditions, no trains are running from A to B. Instead of this, the train company operates a bus from A to B. Then, riders transfer to the train and get to their destination (station C). They call this a "bimodal service".
Considering this I created two routes: One with route_type = 3 (bus) and the another one, with route_type = 2 (train).

The first route (bus) runs a trip from A to B and the second one (train), from B to C.

So the problem is that this configuration allows riders to plan a trip by bus from A to B and this is strictly forbidden. Riders only can travel from A to C or B to C.

I hope there is a way for riders from station A to use station B only for transfers, with no possibility of leaving the station.

Thank you for your help.

So, what happens when you get off the train at B? Is it some sort of prison that you are not allowed to leave?

Good question. You must check your luggage at station A and go through baggage claim at station C. Someone trying to get off at station B may create delays. Also that's why you can't buy a ticket from A to B or arrange a drop off with customer service.

But it sounds like you want to disallow getting off and then leaving the station while you want to allow getting off and walking to the train. Something like that doesn't exist to my knowledge.
